Ms Forcada told La Vanguardia newspaper that the email she received made her feel “insulted as she could do the job as well as any man”.

She said she received a later email offering her a job opportunity because “someone in the company knew her”.

To show her anger at the discrimination that she believes she experienced, Ms Forcada tweeted at clients who had contracts with Impulsa Comunicación.

Coca-Cola said that they would not work with the agency any more and expressed their discomfort at Ms Forcada’s experience.

In a tweet, they said that they support companies which have “an inclusive, diverse and equal hiring policy. We are very sorry that our name has been aligned with this discriminatory and unfortunate response”.

Impulsa Comunicación has shut down its website. However its director, Pere Terés, told the Spanish newspaper ABC that the situation was a “misunderstanding” and that “in no circumstance would the company accept discrimination”.
